mini grease groove bullets

[derskeeter]

Thank you for the replies. The bullet I was talking about is actually a 540 grain, BACO #459542. The rifle is an original receiver I got in a paper bag. The barrel is a Pac-Nor 18 twist stainless super match, 32 inches long. It shoots the BACO 435 grain money bullet very well but have since learned I need more bullet weight for the wind.
Wiping between shots was what I figured they were doing. From what I have seen here in Washington state at the match everyone was blow tubing. I'm still leaning toward the 535 grain bullet with the tapered driving band to start. Maybe trying to keep it simple to start with might be the smart way to get into this.
